For example, imagine that the PIR detector actively detects something during 2 seconds, do we have a continuous flow during 2 seconds or only on saying the PIR detector was active during 2 seconds ?
As I understood, the RFXCOM sensor only transmits every n seconds, so my first hypothesis is not realistic but the second one?
Why this question? In order to simulate through a computer what could be done with electronics: a retriggerable monostable.
I'd prefer using a keyboard rather a soldering iron

Thank you,
